Abstract (en)

[origin: US6014011A] A battery charging system for cellular telephones or other portable devices is incorporated into a clock radio. A user is enabled to specify a time-of-day at which s/he wants to be reminded to insert the rechargeable battery into the charging system if re-charging is needed. No alarm is generated if the battery is already in the charging system at the appointed time. A low power radio frequency signal attempts to interrogate the portable device on the assumption that it is within radio range at that time so as to determine the current battery charge status at about the time that the alarm would be generated. If the charging system receives a return signal from the portable device which indicates, or from which it can be determined, that charging is not needed, then the alarm is not generated after all. Otherwise, the alarm is, in fact generated.
